eSCI

Three enhanced serial communications interface (eSCI) modules provide asynchronous

serial communications with peripheral devices and other MCUs, and include support to

interface to Local Interconnect Network (LIN) slave devices. Each eSCI block provides the

following features:

●

Full-duplex operation

●

Standard mark/space non-return-to-zero (NRZ) format

●

13-bit baud rate selection

●

Programmable 8-bit or 9-bit, data format

●

Programmable 12-bit or 13-bit data format for Timed Serial Bus (TSB) configuration to

support the Microsecond bus standard

●

Automatic parity generation

●

LIN support

–

Autonomous transmission of entire frames

–

Configurable to support all revisions of the LIN standard

–

Automatic parity bit generation

–

Double stop bit after bit error

–

10- or 13-bit break support

●

Separately enabled transmitter and receiver

●

Programmable transmitter output parity

●

2 receiver wake-up methods:

–

Idle line wake-up

–

Address mark wake-up

●

Interrupt-driven operation with flags

●

Receiver framing error detection

●

Hardware parity checking

●

1/16 bit-time noise detection

●

DMA support for both transmit and receive data

–

Global error bit stored with receive data in system RAM to allow post processing of

errors

FlexCAN

The SPC564A80 MCU includes three controller area network (FlexCAN) blocks. The

FlexCAN module is a communication controller implementing the CAN protocol according to

Bosch Specification version 2.0B. The CAN protocol was designed to be used primarily as a

vehicle serial data bus, meeting the specific requirements of this field: real-time processing,

reliable operation in the EMI environment of a vehicle, cost-effectiveness and required

bandwidth. Each FlexCAN module contains 64 message buffers.
